Problem

when i train the model , i meet the problem : Caused by op u'Gather_12', defined at: File "/home/dcl/workspace/Pixel2Mesh/train.py", line 55, in model = GCN(placeholders, logging=True) File "/home/dcl/workspace/Pixel2Mesh/p2m/models.py", line 126, in init self.build() File "/home/dcl/workspace/Pixel2Mesh/p2m/models.py", line 91, in build self._loss() File "/home/dcl/workspace/Pixel2Mesh/p2m/models.py", line 136, in _loss self.loss += .1*laplace_loss(self.inputs, self.output1, self.placeholders, 1) File "/home/dcl/workspace/Pixel2Mesh/p2m/losses.py", line 34, in laplace_loss lap1 = laplace_coord(pred1, placeholders, block_id) File "/home/dcl/workspace/Pixel2Mesh/p2m/losses.py", line 27, in laplace_coord laplace = tf.reduce_sum(tf.gather(vertex, indices), 1) File "/home/dcl/conda/envs/new_tf2/lib/python2.7/site-packages/tensorflow/python/ops/array_ops.py", line 2409, in gather validate_indices=validate_indices, name=name) File "/home/dcl/conda/envs/new_tf2/lib/python2.7/site-packages/tensorflow/python/ops/gen_array_ops.py", line 1219, in gather validate_indices=validate_indices, name=name) File "/home/dcl/conda/envs/new_tf2/lib/python2.7/site-packages/tensorflow/python/framework/op_def_library.py", line 767, in apply_op op_def=op_def) File "/home/dcl/conda/envs/new_tf2/lib/python2.7/site-packages/tensorflow/python/framework/ops.py", line 2630, in create_op original_op=self._default_original_op, op_def=op_def) File "/home/dcl/conda/envs/new_tf2/lib/python2.7/site-packages/tensorflow/python/framework/ops.py", line 1204, in init self._traceback = self._graph._extract_stack() # pylint: disable=protected-access

same problem. InvalidArgumentError (see above for traceback): flat indices[117, :] = [3, 7] does not index into param (shape: [7,7,512]). [[Node: graphprojection_1/GatherNd_15 = GatherNd[Tindices=DT_INT32, Tparams=DT_FLOAT, _device="/job:localhost/replica:0/task:0/device:CPU:0"](gcn/Squeeze_3, graphprojection_1/stack_15)]]
